New Yorkers vote at M.S. 114 on East 91st Street in Manhattan during last November's local elections.

Despite alarming and repeated warnings from the U.S. intelligence community, the country's voting systems remain outdated and could once again be susceptible to Russian hacking when Americans head to the polls for this year's midterm elections, according to a new study.

The FBI, the CIA, the NSA and other intelligence agencies called for a rigorous overhaul of the American voting system after it became clear that Russians had managed to penetrate voter rolls and spread misinformation throughout the 2016 election season.

But an extensive analysis by New York University's Brennan Center for Justice released Thursday shows that 41 states will use voting machines that are at least a decade old for the upcoming midterms. Forty-three states will be using machines that are no longer produced, the same figure as in 2016. Only three states — Colorado, New Mexico and Rhode Island — have improved their systems in any way, the study found.

Experts are concerned that the outdated systems can easily malfunction, as some of them are unable to support beefed up software meant to prevent hackers.

National Security Agency Director Mike Rogers testified before Congress last month that Russians are gearing up to meddle in this year's midterms. But, Rogers complained, President Trump had nonetheless not issued any policy directives that would allocate resources toward confronting Russian hackers.

"I need a policy decision that indicates there is specific direction to do that," Rogers added.

Trump — whose campaign is being actively investigated for possible collusion with the Kremlin — has faced criticism for not taking the threat of Russian meddling seriously.

Special counsel Robert Mueller indicted 13 Russian nationals last month on a laundry list of charges over their illegal efforts to undermine American democracy, disparage Hillary Clinton and elect Trump.
